Łożyska kulkowe czteropunktowe to promieniowe jednorzędowe łożyska kulkowe skośne z bieżniami zaprojektowanymi do przenoszenia obciążeń osiowych w obu kierunkach. Dla danego obciążenia osiowego można również przenieść ograniczone obciążenie promieniowe (stosunek obciążenia). Łożyska są rozłączne, co oznacza, że pierścień zewnętrzny z zespołem kulek i koszyków można montować oddzielnie od dwóch połówek pierścienia wewnętrznego.
